HOSE-ATTACHING DEV'CE.

Application filed February 8, 1913. Serial No, 747,103.

T0 ail ywhom z'i, may concern Be it known that, I, CHARLES Eutin, a citizen of the United States, residing at New York, in the county of New York and State ot New `i'orl, have invented or discovered certain new and useful Improvements in llege-Attaching Devices, ot which the following is a specification, reference being had therein to the accompanying drawings.

ln attaching a ruhher hose-to a fanret. or similar water delivery spout, as is done in hath tubs and barber shops where a hose oi this kind frequently employed in'connection with sprinklers or spray devices, for shampooing or the like, considerable difliculty or annoyance has heen experienced o ving to the fact that the hose sometimes becomes detached from the faucet or water spout under a heavy pressure of water, and a spilling or squirting of the water about often results.

This invention has for its object to ohviate this diticulty by providing a convenient, device by which a ruhher or other flexible hoscinay he securely attached or coupled to a faucet. or Water spout, or a gas delivery pipe or nozzle, in such a manner that it cannot heroine accidentally detached. This improved device includes a series of pivoted clamping arms between which and the exterior ot the water delivery pipe or nozzle the hose is interposed, these clamping arnis'heing acted on 'by an encircling rotatabley ring which forces them against the' hose, and which is provided with a spiral track into which a stationary pin projects, so that when said sleeve turned it will be caused to travel ondwisc to engage or release said clamping arms.

In the accoml'ianying' drawinwfT Figure 1 is a sectional elevation illustrating one 'torin of the invention. Fig'. 2 is a scetion on line Q--2,Van.l Fig. 3 is a section on line 3h43, Fig. 1. Figs. 4 and $3 illustrate modified .forms of clamping; rings.

Referring to the drawing, 1.2 denotes a pipe or nozzle to which a rubber or other flexible hose i3 is to he attached, said pipe or nozzle, in the construction shown, having an attaehed sleeve l't provided with four radially extending lugs or projections 15 to each of which is pivoted a depending quadrant clamping arin 1G, these Clamping arms being curved transversely to fit. against the hose. Encircling the clamping arms 1G is a cylindrical rotatable clamping ring or sleeve 'shown as laving a Spiral slot :2i/2

n fr reet-ion or the other it will he @nosed tov o travel endwise, either for the pnrposo towing the ciampi ng arms against; the hose or for releasing said arm 'The pin lorated between. two of said ings or pri jections. shown in `Fig. 2. downmrd travel of the ring' t7, wi i the latter in full clamping position, the urine 1li are 'provided at their free ends slight radial projections or time; C; 20 which the lower end ot the said rin ahnt.

.in the forni o the invention shown in i7 4, a stop for the. downward n'iovenient o; the clamping ring 17 is atlorded hy a tiene 2l. at the upper end of the said ring that the downward movement of said hing will he limited by the engagement of said fiange with the radially extending or projections 14, or with the pin i9. lnstead of a solid clamping ring, in 'which the si. ral groove or track is formed, the clamp ing ring may be made ot thin metal, illustrated in Fig. 5, in which the ring '1?0 y extending from one end to the other thereof, and which slotprovides a track to be entered hy the' pin '19. rlhis forni of clamping ring, lining .made ot thin metal, s brass,w\,vliirn if: Sonnrh what resilient, provides an elastic clamping ring which yieldingly grips the clamping arms. In all of these forms of the invention the clamping and holding rings or sleeves are of a length approximately equal to the. length ot' the clamping' arms, so as to inelose and cover said arins when the parte are in clamping position, and thas the. pling presents n neat and attractive appear-- ance. v

The pipe or nozzle l2 is preferably' provided With a tapered lower end 23 to facilitate placing the rnhher hose in operative position, and the said pipe or nozzle is preterahly provided cxteriorly with a series of encircling: ribs or heads Q4, forming a corrugated construotion, and the interior faces of the clamping arms 15 are preferably provided with grooves 25 registering with said rihsy or heads, By virtue ot1 this Constructii'm the 'loxihle hose will'he stri'ingrly gripped and more securely retained in place than it otherwise would he; and although the. rib and groove construction of the nozzle and To limit the teriorl y to said pipe gripping arms is preferred the invention is not to be understood as being limit d thereto, as siilie'ient gripping pressurerinight be secured without it. i

From the foregoing it will be understood that the invention provides inexpensive and convenient means for holding a iexible hose in place on a pipe or delivery nozzle, while the construction is suoli, owing to the somewhat steep pitch of the spiral track or groove of the clamping ring, that the latter may be quickly moved to clamping or unclaniping position simply by two or three turns thereof. The invention will be ticularly useful in securely coupling a exible hose to a gas `delivery pipe or nozzle where an accidental uncoupling might result seriously from the escape of gas.

Having thus described my invention I claim and desire to secure byLetters Patent:

l. The combination with a. pipe or del/ivery nozzle series of pivoted clamping arms disposed exterior-ly to said pipe or nozzle, and a ring adapted to encircle said arms and having a spiral track entered by said pin, so that by turning said ring the latter will be caused to travel endwise into clamping or unclainping position.

2. The combination with a pipe or delivery nozzle provided with a lixed pin, of a series of pivoted clamping arms disposed ex or nozzle, a ring adapted to encircle said arms and having a. spiral track entered by said pin, so that by turning said ring the latter will be caused to travel endwise into clamping or unclamping position, and means foi-limiting the traveling movement of said ring.

3. The combination with a pipe or delivof clamping arms provided witli a fixed pin, of a' 'ery nozzle provided lwith a Afixed pin and with radial lugs or projections, of a series pivoted to said lugs or projections and disposedexteriorly to said pipe or nozzle, and a ring of a length approximately equal to the length of `said clamping arms and being thus adapted to encircle and inclose or cover the same, said ring having a spiral track entered by said pin.

4. The combination with a pipe or delivery nozzle with radial of clamping arms pivoted vto said lugs or projections and disposed exteriorly to said pipe or nozzle, and a cylindrical ring or sleeve adapted to` inclose said arms and said lugs or projections and having a spiral track entered by said pin.

5. The combination With a pipe or delivery nozzle provided with a xed pin `and with radial lugs or projections between two of which said pin is located, of a series of clamping arms pivoted to said'lugs or projections and disposed eXteriorly to said pipe or nozzle, and a cylindrical ring or sleeve adapted to inclose said arms and said lugs or lugs or projections between two V4projections and having a spiral track entered by said pin, nozzle having exterior encircling ribs or" a portion of said pipe or beads, and the interior faces of said clampwhich said pin is located, of a series of Y provided with a fixed pin and ing arms having grooves registering with said ribs or beads.

ln testimony whereof I aliix my signature,

in presence of two witnesses. CHARLES ELKIN.
